Cognitive Psychology
Study of internal mental processes like thinking, knowing, learning
Metacognition
Active control and awareness of one's thinking process
Prototype
Best example or mental image of a concept
Divergent Thinking
Process of generating ideas by exploring various solutions
Problem Solving
Mental process to discover, analyze, and solve problems
Algorithms
Step-by-step procedures for solving a problem
Heuristics
Educated guess based on prior experiences to narrow solutions; rule of thumb
Representativeness Heuristic
Comparing a situation to a mental prototype
Availability Heuristic
Basing decisions on readily available examples
Insights
Sudden realization of a problem solution; Aha! Moment
Wolfgang Kohler
Studied chimps attempting to reach bananas
Functional Fixedness
Viewing problems in a customary manner
Confirmation Bias
Seeking information that supports preconceptions
Belief Perseverance
Clutching to beliefs despite contradictory evidence
Overconfidence
Overestimating one's knowledge, skill, or judgment
Hindsight Bias
Tendency to view events as more predictable in hindsight; "I knew it all along"
Framing (Cognitive Bias)
Presenting an issue in a way that influences decisions
Memory
Persisted learning stored and retrieved over time
Information Processing Model
Compares memory to a computer in encoding, storage, retrieval
Encoding
Process of inputting information into memory
Automatic Processing
Effortless processing of information like space, time, frequency
Effortful Processing
Encoding requiring attention and conscious effort
Storage
Creating a permanent record of encoded information
Retrieval
Recalling stored information when needed
Recall
Accessing information without cues
Recognition
Identifying information after experiencing it
Recollection
Reconstructing memory
Fergus Craik & Robert Lockhart's Levels-of Processing Model
Memory retention based on depth of processing
Shallow Processing
Basic encoding based on appearance
Deep Processing
Attaching meaning to information for better retention
Atkinson-Shiffrin Three-Stage Model of Memory
Memory systems categorized by time frames
Sensory Memory
Brief holding of external sensory events
Iconic Memory
Visual sensory memory
Echoic Memory
Auditory sensory memory
Haptic Memory
Tactile sensory memory
Short-Term Memory
Immediate awareness of information
Long-Term Memory
Retention of memories beyond seconds
Memory Span
Number of items recallable from short-term memory
Chunking
Grouping information into larger units for memory
Linguistic Determinism "Language & Thought"
Whorf's hypothesis that language determines the way we think
Phonemes
The smallest units of sound
Morphemes
The units of meaning, i.e. words and meaningful parts of words (suffixes and prefixes)
Explicit "Conscious" Memory (Declarative Memory)
Information that you have to consciously work to remember
Episodic Memory
Long-term memory that involves the recollection of specific events, situations, and experiences
Semantic Memory
These are memories of facts, concepts, names, and other general knowledge
Implicit "Unconscious" Memory
Information that you remember unconsciously and effortlessly
Procedural Memories
How to perform a specific task, you don't have to consciously recall how to perform these tasks
Eidetic Memory
A person has visual images clear enough to be retained for seconds and realistic in their vividness
Long-Term Potentiation (LTP)
Strengthening of a synaptic connection that happens when the synapse of one neuron repeatedly fires and excites another neuron
Storage Decay, Hermann Ebbinghaus
First to conduct experimental studies on memories by using himself as a subject
Forgetting Curve
The exponential loss of information shortly after learning it
Amnesia
Occurs when a person experiences the full or partial loss of memory, injury, or trauma can create problems with various brain functions
Retrograde Amnesia
Cannot remember things that happened before the event that caused their amnesia
Anterograde Amnesia
Condition in which a person is unable to create new memories after an amnesia-inducing event
Serial Position Effect
When we try to retrieve a long list of words we usually recall the last words and first words best, forgetting the words in the middle
Baddeley's Working Memory
System in your brain that allows you to temporarily retain and manipulate the stored information involved in a complex process
Maintenance Rehearsal
Straight repeating of information in order to memorize it to prolong its presence in STM, can increase the length of time information can be stored to about thirty seconds
Flashbulb Memories
Refer to emotionally intense events that become "burned in" asa vivid-seeming memory
Mood-Congruent Memory
Refers to the tendency to selectively recall details that are consistent with one's current mood
Proactive Interference
Occurs when past information interferes with learning new information
Retroactive Interference
Occurs when new stimuli/learning interferes with the storage and retrieval of previously formed memories
The Misinformation Effect
Incorporating misleading information into one's memory of an event
Fluid Intelligence
Refers to the ability to reason and think flexibly, tend to diminish with adult aging
Crystallized Intelligence
Refers to the accumulation of knowledge, facts, and skills that are acquired throughout life, tend to increase with age
Flynn Effect (James Flynn)
IQ scores have been rising worldwide
